This lesson on the use of Docker is intended to be relevant to a wide +range of researchers, as well as existing and prospective technical +professionals. It is intended as a beginner level course that is +suitable for people who have no experience of containers.

+

We are aiming to help people who want to develop their knowledge of +container tooling to help improve reproducibility and support their +research work, or that of individuals or teams they are working +with.

We provide more detail on specific roles that might benefit from this +course on the Learner Profiles page.

    What makes this especially important? With research being +increasingly digital in nature, more and more of our research outputs +are a result of the use of software and data processing or analysis. +With complex software stacks or groups of dependencies often being +required to run research software, we need approaches to ensure that we +can make it as easy as possible to recreate an environment in which a +given research process was undertaken.
